 We found a bug in export process that prevents post data changes going to
 actual export.
 In wp\wp-admin\includes\export.php L416 you select all matching posts from
 DB, having $posts array of stdClass objects as result. Then you call
 setup_postdata for every post, that goes to wp\wo-includes\query.php
 setup_postdata which calls  $wp_query->setup_postdata after passing the
 $post.
 In function setup_postdata L4754 you check instance of the $post which
 will always be stdClass and create a new $post object. It breaks the
 reference link original $post from export.php so all changes in function
 setup_postdata will not be reflected to original object.

 A possible fix would be converting $post object to WP_Post before calling
 setup_postdata in expost.php Please see patch attached
